New Study Raises Big Questions on U.S. Fugitive Methane Emissions

A new study in the Proceedings of the National Academy of Sciences sheds light on a question that continues to vex industry executives and policymakers alike: How significant are fugitive methane emissions from oil and gas production?

UNEP Report Finds Significant “Emissions Gap” Must Be Bridged

A new report from the U.N. Environment Programme (UNEP) shows that the world is still not taking enough action to avoid dangerous levels of climate change. Assuming countries deliver on the pledges they have made to reduce their respective emissions, the Emissions Gap Report finds that global GHG emissions in 2020 will still be 18 to 27 percent above where they need to be if warming is likely to be limited to 2 degrees Celsius above pre-industrial levels. This gap puts the world in a dangerous position of experiencing increased sea level rise, forest fires, and other serious impacts--unless we take action now.

WRI Launches Upgraded Climate Data Explorer

The world of open data welcomed a new platform this summer—WRI’s Climate Analysis Indicators Tool, or CAIT 2.0. The platform offers free online access to global greenhouse gas (GHG) emissions and other climate data, enabling researchers, policymakers, media, and others to download, visualize, and share data for analysis and communications on climate change.

Today we’re pleased to roll out the next iteration of CAIT 2.0, featuring improved functionality and other upgrades. Check out a screencast of how CAIT 2.0 works, or read on to learn about some of the benefits visitors can expect to find.

Designing the 2015 Climate Agreement: Options for Submitting “National Offers”

The UNFCCC negotiations are entering a crucial phase. Negotiators decided nearly two years ago to establish an international climate action agreement “with legal force” by 2015. How this agreement will be structured, though, remains to be seen.

WRI’s new working paper lays out the various options for designing the process for submitting "national offers," countries’ plans to reduce their respective greenhouse gas emissions. It will be critical for negotiators to focus on three key areas: the content of the offers, the timing and process for submitting them, and how they will be reviewed.

A Pathway to a Climate Change Agreement in 2015: Options for Setting and Reviewing GHG Emission Reduction Offers

The UNFCCC Parties need to put forward emission reduction offers as part of the 2015 climate change agreement that is currently being negotiated. This paper suggests options for the design of this process, including the content of the offers and how they will be reviewed. Ensuring that this...

5 Ways Pennsylvania Can Reduce Power Plant Emissions

Pennsylvania is generating more electricity than it has in the past, but the good news is that it’s doing so while emitting less carbon dioxide pollution. In fact, new WRI analysis finds that Pennsylvania can reduce its CO2 emissions 21 percent below 2011 levels by 2020 just by complying with current policies and taking advantage of existing infrastructure. Achieving these reductions will allow Pennsylvania to meet moderately ambitious EPA power plant emissions standards, which are due to be finalized in 2015.

Power Sector Opportunities for Reducing Carbon Dioxide Emissions: Pennsylvania

President Obama announced the first-ever National Climate Plan for the United States in June 2013. Under the plan, the U.S. Environmental Protection Agency (EPA) will set carbon pollution standards for power plants. In September 2013, EPA introduced emissions standards for new power plants and...

World’s Carbon Budget to Be Spent in Three Decades

EDITOR'S NOTE 11/18/13: After this blog post was published, the IPCC updated its Summary for Policymakers. The figures in this blog post have been updated to reflect new information.

The Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report (AR5) has delivered an overwhelming consensus that climate change impacts are accelerating, fueled by human-caused emissions. We may have just about 30 years left until the world’s carbon budget is spent if we want a likely chance of limiting warming to 2 degrees C. Breaching this limit would put the world at increased risk of forest fires, coral bleaching, higher sea level rise, and other dangerous impacts.

When Will Our Carbon Budget Run Out?

The international community has adopted a goal for global warming not to rise above 2°C compared to pre-industrial temperatures. Scientists have devoted considerable effort to understanding what magnitude of emissions reductions are necessary to limit warming to this level, as the world faces increasingly dangerous climate change impacts with every degree of warming (see Box 1).

IPCC AR5 summarizes the scientific literature and estimates that cumulative carbon dioxide emissions related to human activities need to be limited to 1 trillion tonnes C (1000 PgC) since the beginning of the industrial revolution if we are to have a likely chance of limiting warming to 2°C. This is “our carbon budget” – the same concept as a checking account. When we’ve spent it all, there’s no more money (and the planet’s overdraft fees will be much more significant than a bank’s small charges for bounced checks).[^1]
