Boom and bust 2021: tracking the global coal plant pipeline

A steep increase in coal plant development in China offset a retreat from coal in the rest of the world in 2020, resulting in the first increase in global coal capacity development since 2015. A record-tying 37.8 gigawatts (GW) of coal plants were retired in 2020, led by the U.S. …

Changing our ways? Behaviour change and the climate crisis

The world’s “polluter elite” must be the focus of government policies to tackle the climate crisis, a new report has urged. Across the globe, the wealthiest 10 per cent of people accounted for nearly half of the growth in CO2 emissions associated with consumption habits from 1990 to 2015 – …

Accounting for well-to- wake carbon dioxide equivalent emissions in maritime transportation climate policies

This briefing paper outlines a methodology for calculating well-to-wake CO2-equivalent emissions from four fossil marine fuels: heavy fuel oil, very low sulfur fuel oil, marine gas oil, and liquefied natural gas. Well-to-wake emissions, or life-cycle emissions, are the sum of upstream (well-to-tank) and downstream (tank-to-wake) emissions. In addition to CO2, …

The evolution of commercial vehicles in China: A retrospective evaluation of fuel consumption standards and recommendations for the future

China’s fuel consumption standards for heavy-duty vehicles (HDVs) have progressed since Stage 1 was first introduced in 2012, and Stage 4 standards are currently in development. However, to date there has been no independent retrospective assessment of the impact of Stage 1 and Stage 2 standards, including whether they spurred …

Low-cost carriers and U.S. aviation emissions growth, 2005 to 2019

This report provides the first bottom-up, detailed fuel consumption inventory for all commercial flights to, from, and between U.S. airports using our Global Aviation Carbon Assessment (GACA) model. The analysis finds that overall fuel burn and, therefore, carbon dioxide (CO2) emissions from U.S. airlines increased by 7% from 2005 to …

Peaking and net-zero for India’s energy sector CO2 emissions: an analytical exposition

This CEEW study is the first-of-its-kind exercise to outline multiple pathways for India to attain net-zero emissions, rather than fixating on a single scenario or a single year. The study focuses on insights related to four alternative scenarios: 2030 peak–2050 net-zero, 2030 peak–2060 net-zero, 2040 peak–2070 net-zero, and 2050 peak–2080 …

Assessing the impact of energy prices on plant-level environmental and economic performance: Evidence from Indonesian manufacturers

This paper provides an empirical analysis of the impact of energy price increases – induced notably by the removal of fossil fuel subsidies – on the joint environmental and economic performance of Indonesian plants in the manufacturing industry for the period 1980-2015. The paper shows that a 10% increase in …

China’s new growth story: Linking the 14th Five-Year Plan with the 2060 carbon neutrality pledge

This paper discusses how China’s low-carbon transition can act as a new driver of growth in the post-COVID-19 era. It argues that China should peak its carbon emissions during the 14th Five-Year Plan, which covers the period 2021 to 2025, and bend the emissions curve quickly, in order to achieve …

Scaling-up the recognition of indigenous and community land rights: opportunities, costs and climate implications

This technical report analyzes costs and opportunities for scaling-up the recognition of the collective tenure rights of Indigenous Peoples, local communities, and Afro-descendants as a viable pathway to confronting climate and biodiversity crises. The authors reviewed recent findings that demonstrate the possibility of rapidly scaling up formal recognition of collective …

Carbon capture, use and storage (CCUS)

A new report from the United Nations warns that time is running out to deliver on the Paris Agreement and the 2030 Agenda for Sustainable Development and calls for rapid deployment of carbon capture use and storage (CCUS) to meet carbon neutrality targets. Carbon capture use and storage (CCUS) is …

Fuel consumption reduction technologies for the two-wheeler fleet in India

The shift from carburetor technology to fuel injection that has come with the implementation of India’s Bharat Stage VI emission standards provides the basis from which to consider other incremental technologies for fuel efficiency improvement in the two-wheeler segment, which currently consumes more gasoline than all other forms of on-road …

From dirty oil to clean batteries

An electric vehicle (EV) battery uses up just 30kg of raw materials with recycling compared to the 17,000 litres of petrol burned by the average car. That’s according to a new study that shows Europe’s current crude oil dependency far outweighs its need for battery raw materials. The gap is …

Building back greener: India Inc. demonstrates climate resilience - India annual report 2020

A growing number of Indian companies are beginning to recognise the climate crisis and are committing to tackle climate change by disclosing data through CDP - the first step towards achieving corporate climate goals. Disclosing helps a company get ahead of the curve and prepare for potential market fluctuations and …

World energy transitions outlook: 1.5°C pathway

The World Energy Transitions Outlook preview outlines a pathway for the world to achieve the Paris Agreement goals and halt the pace of climate change by transforming the global energy landscape. This preview presents options to limit global temperature rise to 1.5°C and bring CO2 emissions closer to net zero …

Coal mine methane on the brink

A frenzy of new mine projects and proposals in some of the world’s gassiest coal seams could emit enough methane to rival the current CO2 emissions from coal plants in the United States, according to new data and modeling from Global Energy Monitor. In a first-of-its-kind analysis, GEM has modeled …

Toward a tradable, low-carbon product standard for steel: policy design considerations for the United States

Steel production in the United States accounts for around 100 million tons of carbon dioxide equivalent emissions. Available and emerging technologies have the ability to significantly decarbonize the steel industry. A low-carbon product standard for steel in the United States can incentivize the adoption of these technologies and result in …

The potential role of carbon pricing in Thailand’s power sector

Thailand is committed to playing its part in the international efforts aimed at addressing climate issues. As it is for most countries, the power sector in Thailand is among the largest emitters, accounting for 38% of energy-related CO2 emissions. Hence, reducing the emissions from this sector is fundamental in reducing …

Governing large-scale carbon dioxide removal: are we ready? - an update

Because of the international community’s delay in cutting carbon emissions, some degree of reliance on carbon dioxide removal (CDR) options is now inevitable to achieve the Paris Agreement’s long-term temperature goal. This report seeks to answer questions regarding implementation of CDR options at scale. Can the sustainability challenges, risks and …

Reducing aircraft CO2 emissions: The role of U.S. federal, state, and local policies

In January 2021, the U.S. Environmental Protection Agency (EPA) finalized a domestic aircraft carbon dioxide (CO2) standard that closely follows the international standard adopted by the International Civil Aviation Organization (ICAO) in 2016. This standard will go into effect for all new aircraft delivered in 2028 and thereafter, and previous …

India’s progress in meeting its climate goals: A comparative analysis using country-reported and external data

Recent studies analyzing India’s decarbonisation efforts using external data do not confirm the achievements stated in India’s country reports submitted to the United Nations Framework Convention on Climate Convention. The role of economic structure changes compared to energy intensity in driving India’s carbon dioxide emissions also differs across studies using …
