    Discussion Draft: The Economic Impact at the National Level of the Illegal Conversion of Forests for Export-Driven Industrial Agriculture


    Between 2000-2012, half of all tropical deforestation was the result of illegal clearing for industrial agriculture (Lawson et al. 2014).  This report aims to characterize the costs of this illegality.  While the impacts are widespread, including global, we focus our analyses on the costs to the countries in which the deforestation occurs.  We hope a broad estimate of financial loss will help convince forest country actors, like Finance Ministers, of the gains to be made by enforcing laws and regulations related to land use for industrial agriculture.

    Illegal clearing creates losses by undermining a country’s objectives for the management of its natural resources, like land and forests, which include, inter alia, promoting:

    • Economic activity that generates jobs, investment, as well as tax revenue;
    • Production of timber and non-timber forest products, as well as the maintenance of ecosystem functions like climate stabilization;
    • Contribution to the lives and livelihoods of rural people; and,
    • Protection of the rights of indigenous people, forest-owners, and forest-users.

    Blockchain: the missing link between climate finance and forest conservation?

    By Erika Drazen and Peter Graham

    If you haven’t heard of blockchain yet, you soon will. From its beginnings as a system for verifying Bitcoin transactions, blockchain is now sweeping the world of finance and expanding into other areas of business and public policy. And it’s already being touted as a tool for facilitating climate-related transactions, including results-based payments for REDD+ – as outlined in a recent policy paper from Climate Advisers, Lestari Capital and Lykke.

    So, what exactly is blockchain? In the jargon, it’s a distributed ledger technology (DLT), which uses a peer-to-peer network to securely verify and record financial and other transactions. Instead of relying on information stored in a central location, such as a single company’s database or server, DLT distributes the data associated with the transaction across an open network. This decentralized process makes it almost impossible to tamper with the data. Read more >

    Tax Reform: A $1.5 Trillion Missed Opportunity, For Now

    By Nigel Purvis and Maria Belenky

    Last month, budget-conscious Congressional Republicans passed a massive tax reform package that will likely add at least $1.5 trillion to the U.S. federal deficit over the next 10 years. But here’s the thing—it didn’t have to. One sensible and responsible revenue-raising option would have gone a long way in helping to close the funding gap: a carbon tax.

    Earlier this year, Climate Advisers and ecoAmerica calculated that imposing a $25 tax on every ton of greenhouse gas emissions released into the atmosphere—a relatively low rate in most environmental circles—would raise over trillion dollars in revenue over the next ten years. Just this one revenue source, if used in its entirety to address the deficit, would offset two-thirds of the funding gap left open by the tax reform package. Trimming off funds to provide assistance to households who may face higher energy prices would still leave a sizable sum for corporate tax reductions and other conservative priorities.
