    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.

    Ceres Launches Engage the Chain Case Studies on Business Risks from Deforestation

    By Anthony Mansell and Gabriel Thoumi

    Companies that fail to manage their environmental performance expose themselves to business risks. Rising consumer and investor awareness about the environmental and social impacts of deforestation is placing increased scrutiny on companies that source commodities from high-risk deforestation, to ensure that their products are not sourced with illegal or questionable environmental practices. Companies that ignore this scrutiny subject themselves to potential regulatory action, or loss of customers, with negative financial consequences.

    This past November, Ceres launched three case studies of companies – IOI Corporation, JBS and United Cacao – that exposed themselves to business risk by failing to address questions about the environmental performance. The full case studies are available here and also on Ceres’ Engage the Chain website.

    • IOI Corporation was suspended from the Roundtable on Sustainable Palm Oil (RSPO) because of 11,750 hectares of land cleared illegally by its Indonesian subsidiaries. With the suspension, RSPO prohibited IOI from selling crude sustainable palm oil (CSPO). This prompted 27 of IOI’s largest corporate buyers to suspend procurement contracts with IOI, leading to a drop in its net income.
    • United Cacao’s illegal deforestation was a leading indicator of the broader corporate governance issues, culminating in its winding-up in July 2017. Its expansion plans conflicted directly with government regulations against deforestation – a risk the company itself identified in its bond issuance. On January 4, 2017, United Cacao’s nominated adviser resigned its role, leading to the suspension of trading of its equity on AIM and its bond on the NEX Exchange, and the delisting of United Cacao from the AIM on February 6, 2017.
    • The case of JBS demonstrates the cascading effect of uncovering actions that generate reputational risk. Investigations by Brazilian authorities into JBS have produced accusations of bribery, financial and accounting violations, labor standards and illegal deforestation. The accusations of deforestation provided additional reasons for investors and trading partners to be suspicious of JBS’ reputation. The cascade of scandals forced JBS to delay its initial public offering (IPO) for its foreign operations through JBS Foods International.

    Risk is broadly defined in this case study series as the volatility of returns that could generate unexpected losses or profits associated with direct and indirect impacts from deforestation. These risks can be market related, such as input or output price volatility and/or loss of market access; reputational, where the firm’s brand equity could be impacted; operational, within the boundaries of the firm’s business activities and processes; or regulatory/litigation, where government actions could impact the firm’s operations or finances.

    Overall, risks impact a company’s balance sheet – their assets, liabilities, equity and valuation – income statement – their revenues, costs, profitability and net income – and cash flow. This often has direct implications for the value of the company’s debt or equity, and passes through to investors. Businesses can measure risks for their expected outcome and the probability that they will occur, and attempt to mitigate or minimize them.

    You can download the case studies here and also on Ceres’ Engage the Chain website.
