A big thing the World Resources Institute has been doing for years is developing a Global Protocol for Community-Scale Greenhouse Gas Inventories (GPC). Rio de Janeiro and 34 other cities have pilot-tested that, and the World Resources Institute, C40 Cities Climate Leadership Group, and ICLEI, are today rolling out the finalized version of the GPC.
Aside from the experience from the pilot cities of the GPC, another 65+ have used early versions of the tool already. The finalized tool incorporates lessons from numerous cities, and it has been in development for three years.
Regarding Rio’s use of the GPC, the World Resources Institute writes: “By using the standard, the city figured out that transport and waste were the biggest contributors to its overall emissions—at 39 percent and 19 percent respectively, and that targeting emissions reductions in these sectors would help meet its 20 percent target.”
This is the nuts and bolts of cutting carbon emissions, and doing so efficiently and effectively. “It’s the first internationally accepted standard for measuring emissions at the city level, and empowers cities to accurately identify where their emissions are coming from, set credible and achievable reduction targets, and consistently track progress,” WRI writes.
