		Operating Ethically
		Except where noted, this report covers all Weyerhaeuser operations for the calendar year 2017. Our environmental data is specific to our operations owned in 2017. We do not include operations sold during 2017, our distribution centers which have an insignificant environmental footprint compared to our manufacturing facilities, nor our offices.
103-2	The management approach and its components	Our Approach, our Company Vision, Code of Ethics and Supplier Code of Ethics create the foundation for the way that we operate. Should any of our stakeholders have concerns about the way that we do business, we encourage them to contact our EthicsLine at 800-716-3488 or use Weyerhaeuser Ethics Online. We set the rights goals and report on our progress. We use a variety of mechanisms to establish and monitor goals, including: -Established internal databases used regularly by our operations. -Environmental data reported to the EPA and other regulatory agencies. -Annual companywide internal surveys. -Physical measurements and representative and other sampling at our facilities. -Standard government factor and recognized industry factors. -Calculations are performed using measured data as well as commonly recognized engineering standards. All equations and estimations used in calculating environmental data are accepted industry wide and by all pertinent regulatory authorities. Each section of this website is drafted and/or reviewed by internal subject-matter experts to ensure accuracy. The final draft of the website is reviewed by key senior leaders and subject-matter experts to ensure the information is accurately communicated, appropriate for public disclosure, and is significant to us and our shareholders.

By far, Scope 1 and 2 GHG emissions are most relevant to our company. In 2013, we evaluated including Scope 3 categories into our GHG inventory, based on WRI’s “Corporate Value Chain (Scope 3) Accounting and Reporting Standards.” Eight of the fifteen Scope 3 categories were considered related to our company, but we have chosen not to initiate this work until customer requests increase to a significant level and industry-specific guidelines are developed to ensure comparability with other forest product companies. We are a large, vertically integrated company, with most of our value chain embedded in our company. The majority of our suppliers are small forest landowners, who are already helping reduce the risk of climate change by managing forest land - nature’s best carbon capturing systems.

403-4	Health and safety topics covered in formal agreements with trade unions	Union representatives play a significant role in safety and health. They participate in joint union-management safety committees and represent workers in joint investigations, coaching and counseling. We first introduced high-performance or total-quality work systems in the late 1970s. These systems are designed to increase employee participation in decisions that affect their jobs and to improve business performance. In our union and nonunion facilities, participative work systems are part of our business strategy and planning. At our facilities with high-performance work systems, process reliability is higher than at our traditionally managed facilities.

GREENHOUSE GAS INVENTORY METHODOLOGY

Our estimates of greenhouse gas emissions and carbon sequestration represent our corporate carbon scope 1 (direct) and scope 2 (purchased electricity) inventory. They do not include emissions not owned or controlled by Weyerhaeuser.

Our greenhouse gas inventory process adheres to the guidelines published by the Greenhouse Gas Protocol Initiative's Greenhouse Gas Protocol, Revised Edition, and its associated calculation tools that are relevant to our operations. Following the protocol, adjustments to the baseline year and subsequent years’ data have been made on a whole-year basis for divestments and acquisitions affecting our greenhouse gas inventory. In 2017, we also adjusted our baseline and all subsequent years to correctly account for the appropriate eGRID emission factors for the closest respective year; previously, we incorrectly recalculated all years with the most recent eGRID emission factors. The absolute value of our entire greenhouse gas emission inventory can change as a result of these adjustments.

We know forests sequester and release carbon in variable amounts over time. The rate of forest carbon sequestration is subject to seasonal variation, annual variation due to climate and disturbance impacts, age-related variation due to the natural cycle of tree growth, and effects from forest management practices such as fertilization and harvesting. The U.S. Department of Energy 1605(b) guidelines affirm that sustainably managed forests balance harvest and growth cycles over time and landscape and can be considered carbon neutral, meaning the carbon that is released from harvesting is offset by the growth of the remaining trees. To quantify the amount of long-term forest products carbon stored in our products – which we call Product Sequestration – we use the US Forest Service 100-year average carbon storage estimates approach and a tool produced by a research organization supporting our industry.

Due to the merging of forest inventory and management systems between Plum Creek and Weyerhaeuser, a few values are currently unavailable. We will resume reporting on these values when our systems are fully merged. Some ecosystem services provided by our timberlands do not lend themselves to annual reporting due to a lack of quantitative measures, insufficient reporting units, or the service having been recently discontinued. These services are important reflections of the value provided by our timberlands and could lend themselves to fuller description in the future, if not annual tracking.
