Scoping and feasibility studies of bamboo plantation for implementation of REDD+ activities in the North-Eastern states of India

Land is source and sink of carbon dioxide due to anthropogenic and natural drivers. Global models estimate net carbon dioxide emissions of 5.2 ± 2.6 GtCO2eq yr–1 (likely range) from land use and land-use change during 2007–2016. Agriculture, Forestry and Other Land Use (AFOLU) activities accounted 23% (12.0 ± 2.9 …

WMO Greenhouse Gas Bulletin (GHG Bulletin): The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2019

The industrial slowdown due to the COVID-19 pandemic has not curbed record levels of greenhouse gases which are trapping heat in the atmosphere, increasing temperatures and driving more extreme weather, ice melt, sea-level rise and ocean acidification, according to the World Meteorological Organization (WMO). The lockdown has cut emissions of …

The climate transparency report 2020

The Climate Transparency Report (previously known as „Brown to Green Report”) is the world’s most comprehensive annual review of G20 countries’ climate action and their transition to a net-zero emissions economy. The review is based on 100 indicators for adaptation, mitigation and finance and aims to make good practices and …

Observations, reconstructions and climate modelling …

Clean skies for tomorrow: sustainable aviation fuels as a pathway to net-zero aviation

The World Economic Forum’s Clean Skies for Tomorrow coalition recognises that the most immediate action to achieve carbon-neutral flying is the investment in, and rapid scale-up, of sustainable aviation fuel production and use. This foundational report demonstrates the feasibility, scalability and potential cost of different technological pathways for sustainable aviation …

Potential CO2 reductions under the Energy Efficiency Existing Ship Index

Proposed short-term measures to reduce the carbon intensity of international shipping fall into two categories: operational approaches and technical approaches. Based on the International Maritime Organization’s (IMO) latest “hybrid” proposal, ships will be required to adopt both approaches starting in 2023 to help meet IMO’s minimum 2030 carbon intensity goal. …

Renewable energy pathways in road transport

A rapid and fundamental shift is required in transport to enable the decarbonisation required to meet the objectives of the Paris Climate Agreement, with actors in both the energy and transport sectors working together. To that end, REN21 teamed up with the FIA Foundation to do an in-depth study: Renewable …

China Nationally Determined Contribution (NDC) and Domestic 14th Power Five-Year-Plan (FYP)

This report “China Nationally Determined Contribution and Domestic 14th Power Five-Year-Plan” shows that power industry plans to build new coal-fired power plants after 2020 contradict China’s 2060 carbon neutrality target. The report calls for China to initiate a policy process to phase out coal-fired power plants. At the same time, …

Indicators for sustainable development under Article 6 of the Paris Agreement

This report analyses how the role of sustainable development can be strengthened in the process of further designing the mechanisms under Article 6 of the Paris Agreement. The paper reflects on the experience with sustainable development in past and current market mechanisms and describes to what extent countries agreed on …

America's Zero Carbon Action Plan

A strategy for putting Americans back to work based on advanced technologies, good jobs, clean energy, climate safety, and economic security.

Not Zero: How ‘net zero’ targets disguise climate inaction

This joint briefing highlights concerns that many governments and corporations are jumping on the bandwagon and declaring “net zero” climate targets. These announcements might sound like they signify ambitious climate action. But unfortunately, the “net” in “net zero” is being used to green-wash weak climate targets, and could end up …

Technology roadmap and costs for fuel efficiency increase and CO2 reduction from Chinese new passenger cars in 2030

To support the development of stringent yet cost-effective fuel efficiency standards for Chinese passenger cars for the 2025–2030 time frame, this study evaluates the potential technology pathways for and incremental costs of meeting the preliminary fuel efficiency target outlined in Made in China 2025. Based on methods developed in previous …

Navigating the nuances of net-zero targets

This report analyses the momentum of targets for net-zero emissions across companies, cities and regions worldwide. This report serves as an helpful resource for net-zero target setters on the importance of transparency in both target-setting and implementation. Consumers and citizens are scrutinizing the climate ambitions of non-state actors now more …

Reducing Co2 Footprints of India's Coal-Based Power

Despite the growth in renewable power, India continues to be heavily reliant on coal to meet its energy needs. This is unlikely to change in the near future. India’s coal power sector contributes nearly 50 per cent of India’s fuel-related CO2 emissions. Beset with all kinds of problems, from poor …
